probably when lee gets drunk, he doesn't get as powerful as when opening his gates but probably his moves will be more perfect and unpredictable, now imagine a fighting style that can attack while dodging blows accurately that'll most likely be what happens, his moves will be too unpredictable and too precise for kimimaro to handle thus his downfall, although I do think that when kimi goes into Lvl 2 either Lee will have to open the gates again or he'll be screwed because if he's capable of going against lvl2 kimi then kishimoto will need to think up a damn good explenation for it
